To all'whom it may concern:

Be it known that 1, CHARLES Salt Lake City, in the county of Salt Lakeand State of'Utah, have invented certain new and useful Improvementsin-Safe Locks, of which the following is =a-speciiication.

My invention relates to locks for -safes and vaults, and has forits-object to provide an auxiliary lockor fastening means for safes andvault doors, whichare locked with my auxiliary lock by the custodianwhen the door isclos'ed, and which will be further automatically lockedby any attempt to force the'auxiliary combination look from the outside. A further object is to provide on safe and vault doors, havinghorizontally or vertically movable locking bars which engage the sidesand endsof the'safeor vault when the bolt bars are 'set, :an auxiliarycombination lock b which any one or more of said bars may e lockedandheld'from movement. A'further object is to improve the presentfastening of vault and safe doors by providing means for locking thebolts of said present fastenings with an auxiliary lock ofthe'combination type which automatically set to engage said bolts at anyattempt to force said'auxilia'ry look from the outside of said vault. vl

These objects I accomplish with the device illustrated in theaccompanying drawings in which similar letters and numerals of referenceindicate like parts throughout the several-views and as described in thespecirticationforming apart of thisapplication and pointed out in theappended claii'ns.

In the drawings in which 1 have shown a substantial embodiment of myinvention, Figure l is anelevation of the inside of'the va'ult door in alocked positioinand with the fastening bolts engaged by my auxiliary'lock. -Figure 2 is a view of aportion of :the same door with the boltsshowuinunlocked position'and with my auxiliarylockmeans. Fignot engagedwith the fastenin ure 3 is an elevation of a portion of the outside ofsaid door with the auxiliary combination lock in place thereon inaddition to the regular lock. Figure 4: IS a view partly in section ofone of my locks in place on'one of the fastening bolts and after it hasbeen engaged with said bolt after attempted A. Fownnm a citizen of theUnited States, residing at burglary. Figure 5 is another view showingthe fastening means as they appear when fullyset by an attempt to breakmy auxili ary lock. Figure :6 is a view partly in section of the otherbolt fastening means. F

ures 4, 5 and 6 are somewhat enlarged ..ela-

tive to the other figures The fastening means now used on most safe andvault doors consists of bolts which are moved longitudinally by a leverand which are set against such. movement by a combination lock thatisoperable by any person knowing the combinatioinand frequently set sothat itcan not be worked before a time limit as well. 'Burglars knowingthe construction of such locks andbolts frequently drill holes in thedoor adjacent the lock, sever the connection between the said'lock andthe bolts, or by means ofpunches from outside the door they destroy thelock and can then operate the lever-and move the fastening bolts orshafts as they are sometimes called. invention is to provide anothercombination lock which is secured on the door and by which any one ormoreof said bolts or shafts may be secured against the movement requiredto open the door. This auxiliary locking of said bolts maybeaccomplished and operated by the person whose duty it is to lookthe safeor vault, or if such person should fail or neglect to operate and setsaid auxiliary lock, and any attempt-be made to destroy the auxiliarylook from outside the vault my improved lock will be automatically setand none of said bolts may be thereafter moved or the door be openedwithout its destruc- 'tion,'a-nd, furthery-the--particular bolt or shaftwith which my auxiliary lock is used may be changed from time to time asdesired and its connection with any particular one or more of said boltscan not be determined or ascertained from outside the safe or vault, sothat the connection can be destroyed from any one operating outside thevault, and the connections are purposely made to differ when two or moreare used so that they may not be destroyed or moved by any one notknowing the combination of the auxiliary lock, whether that person worksfrom 'inside' or outside the safe or vault. This is accomplished bytheuse of the cylinder lock shown in Figure 4:.

til

My improved locking means consists of a combination look A, with anydesired number of tumblers, and which is secured in a hole in the doorof the safe or vault. On the inner end of said lock is fastened a disk 1having one or two laterally projecting pins 2 on. its inner face. Ametal frame B is secured to the inner face of the door C and throughwhich frame B is bored opc-nings in which is operatively carried thefastening bolts D. The said bolts D are moved simultaneously by thelever E which moves the cross piece F, and by the bell-crank levers Gwhich are moved by two of said bolts D. On the inner face of said frame13 is provided two bearing or guide sleeves 4: and 5, and within whichare operated the locking bars 6 and 7. The said locking bar 6 is movedby the lever 8 with and by the link bar 10, while the locking bar 7 ismoved by the lever 9 which is connected with said disk 1 by the link bar11. A spring 12 is connected at one end to the lever 8 and at its otherend to the said door C to automatically further move the locking bar 6when the lock A or any of the members 8, 9, 10 or 11 are injured.Another spring 13 is used to similarly operate the locking bar T and setthe catch pin 22 provided in locking bar 7 7 when look A or bars 8, 9,10 or 11 are injured or destroyed. It is obvious that similar lockingbars may be provided for on any of said fastening bolts D as desired, byslight changes in the levers and link bars connecting said bolts withsaid disk 1. The said locking bar 6 is bifurcated at one end, as shownin Figures & and 5, and on one prong shown at 1 1 a lock case H isprovided within which is operated a cylinder lock having a number oftumblers 15 which are operated by a key 16. A spring bolt 17 is providedin said case H to automatically move longitudinally and thereby engagein a recess 18 which is cut in the adjacent fastening bolt D to locksaid locking bar 6 in its engagement with said fastening bolt D. Thelocking bar 7 is to engage the fastening bolt D adjacent thereto bybeing carried in or passed through a hole cut in said bolt D.

The operation of locking any safe or vault door is as follows The keeperof the safe or vault closes the door and fastens it in place by movingthe usual lever E. The common lock used for locking the safe, shown atK, is then set to lock said cross piece F, and by operating thecombination lock K the safe is locked against any opening thereof exceptby burglars. As previously stated, a burglar may drill a hole throughthe door adjacent the racking or connecting bar 21 and saw off said bar,and if that is the only fastening means used, all the burglar will haveto do after sawing said bar 21 is to move the lever E and thereby openthe vault. Or he may punch out the said lock K and thereby destroy thesaid racking or connecting bar 21 and its engagement with said crosspiece F, when the safe may be opened, as before stated. However, if myinvention is used on said vault and the combination lock A is set andthe locking bars 6 and 7 are engaged as shown in Figure 1, and anattempt is made to destroy the said lock A or lovers 8 or 9, saidattempt will move the links 10 and 11 from off the pins 2 and theirrespective springs 12 and 13 will automatically further move the lockingbars (3 and 7 and allow the respective fasteners, pins 17 and 22, totrip, thereby further locking my device, which can not then be openedexcept by use of the key 16. The adjacent fastening bolts D can not bemoved longitudinally until the key 16 is used and the spring bolt 22 isoperated, both of which must be moved and unlocked from inside of thevault. And even though a hole be cut in the door large enough for theburglar to enter he musthave the key and operate the cylinder lock shownin Figure 4 before lie-can open the door. The tire doors providedbetween the vault and safe doors can not be opened far enough forentrance to vault except after the outside door has been fully opened.This is one ofthe purposes of providing the cylinder lock, shown inFigure 4.

Having thus described my invention and its operation, I desire to secureby Letters Patent and claim 1. In an auxiliary lock for safe doors thecombination of longitudinally movable bars slidably carried on the doorand adapted to engage the walls of the safe. of a combination locksecured in said door: a disk secured on the inside of said lock; linksconnected therewith and pivoted to spring actuated levers; locking barsadapted toengage with said longitudinally movable bars and each of saidlocking bars pivoted to its respective lever, whereby said locking barswill be moved longitudinally and engage said longitudinally movable barswhen the said links are disengaged from said disk; and means to releasesaid locking bars when said safe door is fully opened.
